Stripe Sessions 2026 | Developer keynote

AI agents are fundamentally reshaping developer experience, with 91% of Stripe engineers now utilizing AI tools and a 140% surge in AI-assisted pull requests. To optimize this shift, Stripe provides agents with curated context through raw markdown documentation and structured blueprints, ensuring they avoid outdated integration patterns. The platform empowers agents with deterministic tools, including Model Context Protocol (MCP) servers and local sandboxes, enabling end-to-end testing without breaking development flows. Reliability is maintained through agent-tagged API keys and approval guardrails, which restrict autonomous actions like large refunds. Furthermore, integrating custom objects and workflow automation allows agents to move beyond code generation to manage routine business operations, such as customer support and sales notifications, creating a robust, end-to-end development stack that balances speed with necessary human oversight.
